You don’t need to tan or burn your skin to get vitamin D. You only need to expose your skin for around half the time it takes for your skin to turn pink and begin to burn.

Summer is right around the corner, which means lots of fun and sunny times outdoors. But along with the sun comes the threat of sunburn; a major player in skin cancers. At high noon with direct sun it only takes 15 minutes to get sunburn on unprotected skin. People are using sunscreen with increasing frequency, raising the question of the products efficacy and safety.
How Does Sunscreen Work?
The active ingredients within sunscreens absorb, reflect, or scatter UV radiation to subvert skin absorption. There are two main types of UV radiation known to contribute to skin cancer, wrinkling, and premature skin aging: UVA and UVB. Until recently, manufacturers created sunscreens effective only at screening UVB radiation. Sun Protection Factor (SPF) rating measures UVB protection only, so regardless of the SPF, it is important to choose a product labeled as UVA/UVB or “broad spectrum.”
